Mike Keith believe the JDO is out of date. Then what role of JDO in ObjectDB? Will our codes with JDO be out of date? Due in part to some of the failures of the EJB persistence model, and some frustration at not having a satisfactory standardized persistence API, another persistence specification

would have thought that would be done automatically. Having used objectdb for nearly 10 years now, all in
